MACHINE FOR GENERATING FLUID-PRESSURE POWER.

' SPECIFICATION forming part Of Letters Patent No. 566,897, dated September 1, 1896.

Application filed October 14, 1895- Serial No. 565,622. (No model.)

To all whom it may concern:

Be it known that I, ISAAC '1. DY ER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Machines for Generating Fluid Pressure Power, of which the following is a specification.

My invention relates to an improvement in the class of mechanism for compressing fluid (as air, steam, and the like) for use as power by employing the action upon the reciproeating pistons of a series of fluid-pumps of a rolling body to actuate the pumps.

Referring to the accompanying drawings, Figure 1 is a plan view of my improved machine with the ends of the several shafts thereof shown broken away. Fig. 2 shows the same by a broken View in elevation, partly sectional. Fig. 3 is a broken view showing one of the pumps, on an enlarged scale, in sectional elevation; and Fig. 4, a View of the machine in vertical sectional elevation, showing a modification.

A is the bed of the machine, shown in its preferred circular shape, and which should be formed, massively, of metal. According to the construction represented by Figs. 1 and 2 the bed is stationary. At suitable intervals cylindrical wells are formed in the bed to a desired depth from its upper surface to afford the cylinders 1 of air-pumps B, each cylinder containing a piston r on a stem 0*, and depending for its outward stroke upon the recoil of a spring r confined about the stem to be compressed by the inward stroke of the piston, the latter being provided with packing q, and operating, by its upstroke, to suck in atmospheric air through the inletpipe 1), having an inwardly-opening checkvalve 0, and by its downstroke to force the air out through the discharge-pipe p, equipped with an outwardly-opening check-valve o. On the outer end of the piston-stem is pivoted a yoke 0. As shown, three concentric circumferential series of the pumps B areprovided on the bed A, though this number may, of course, be varied according to desire or requirement; and they are placed in such relation to each other, both circumferentially and radially, (though there may be no strictly radial series of the pumps, owing to the variation in the number of members of the several concentric circumferential series,) as to coincide with the points which actuate them upon the rolling bodies, all as hereinafter described. Each circumferential series of the pipes 13 is covered by a cap 10 into which the fluid is discharged from them; and all the caps communicate, through discharge-pipes n, with a common outlet-pipe n, which leads to the point of storage or utilization (not shown) of the compressed fluid.

Extending upward from the center of the bed A is a stationary shaft or post 0, Fig. 2, surrounded at its lower end, adjacent to the bed, by a rotatory head D, and above the head D the post 0 carries, confined between the sleeves t and t, a rotatory beveled gearwheel E, having a separate set of teeth on each of its upper and lower sides. This gearwheel is shown most clearly in Fig. 2. In Fig. 1 of the drawings only a portion of the teeth 011 the upper side of the wheel are shown, the remainder being indicated by broken lines to avoid confusion in the drawmgs.

F is a rotary drive-shaft supported at one end in a suitable bearing 00, provided on the post 0, and, toward its opposite end, in a bearing :0, and it carries a beveled pinion m, meshing with the teeth on the upper side of the beveled gear-wheel E.

G G are rollers, of which four are shown, (although it is within my invention to pr0- vide one or more,) preferably of the tapering shape illustrated, and formed of heavy material, such as iron or stone, to weigh each, say, a ton or more. Each roller is provided with series of recesses Z, containing projections Z, corresponding in relative location with the protruding yokes 0 of the pump-pistons, which these projections encounter in the path of travel of the rollers, as hereinafter described. Each tapering roller rests, to extend radially, upon the upper surface of the bed A and bear its weight against the corresponding series of yokes 0, that may be beneath it, the roller being connected with the rotatory head D by a shaft is, passing lengthwise through the center of the roller (which revolves with the shaft) and j0urnaled atits inner end in a suitable bearing provided in the rotatoryhead. On each roller is a circumferential beveled gear i,with which mesh the teeth on the lower side of the beveled gear-wheel E. As in the case of the wheel E in Fig. 1, to avoid confusion in that figure of the drawings the beveled gears i are merely indicated by broken lines on all the rollers except one.

The operation of the machine involving the construction illustrated in Figs. 1 and 2 is as follows: The driving power (not shown, but which may be any suitable engine) applied to the shaft F rotates it and, through its gear connection with the rollers G, turns them on their own axes, and also about the post 0 with the rotatory head D. In rolling the bodies G the projections Z on each execute, as it were, a step-by-step motion, encountering in each step a series of the yokes 0 on the protruding ends of the pump-piston stems, and, by the weight of the rolling body, producing inward strokes of the encountered pistons and compression of their controllingsprings r and forcing the air which the pistons have sucked into the cylinders by their upward strokes, produced by the recoil of the springs 0, when released, out through the pipes 10 into the common discharge-pipe n. Of course, if steam or other fluid be the fluid to be compressed or pumped, the pipes 19 are suitably connected with the supply thereof, as with an exhaust-steam supply. The number of times each rolling body may be caused to travel the circuit of the bedA in one minute is easily ten, so that then, with four of these bodies provided, each pump will be actuated forty times per minute, and with, say, eighty pumps, each thus actuated forty times, the air-pressure produced in each minute of the operation of the machine is the result of three thousand two hundred pistonstrokes. Instead of causing the rolling bodies G to travel the circuit of the bed, a bed A, carrying the pumps, may, with the same result as that described, be caused to rotate below those bodies and roll them only on their own axes. This may be accomplished by the construction illustrated in Fig. 4. For this purpose a stationary head D may be provided about the rotatory post 0 to afford bearings for the inner ends of the rotary shafts 70, carrying the bodies G, these shafts being supported at their outer. ends in suitable bearings 00 The bed A is supported at s to be rotated with the shaft 0, and is provided with gear-teeth it about its periphery, meshing with a horizontally-disposed pinion m on a vertical drive-shaft F and with gear-teeth it about its upper surface, with which mesh the gears i on the rollers; and the leadingofi pipe at has a tubular extension n formed in the bed A and coinciding at its end with a port a leading to a longitudinal passage 41 in the post 0, from the outer end of which extends a pipe 'n for conveying the generated pressure or pumped fluid to the point of stor- What I claim as new, and desire to secure.
